Gradio Audio Transcription App.
|
|
--------------------------------
|
|
|
|
This module provides an interface to transcribe audio files using the
|
|
Scraibe model. Users can either upload an audio file or record their speech
|
|
live for transcription. The application supports multiple languages and provides
|
|
options to specify the number of speakers and the language of the audio.
|
|
|
|
Attributes:
|
|
LANGUAGES (list): A list of supported languages for transcription.
|
|
|
|
Usage:
|
|
Run this script to start the Gradio web interface for audio transcription.
